Abstract

To determine the characteristics of infectious keratitis related to plano cosmetic lenses.Retrospective case study of a series of infectious keratitis among plano cosmetic lenses wearers. The main parameters were demographic data, medical history, risk factors for infectious complications and keratitis severity criteria, microbiological results, clinical course, and final visual acuity.Five patients were included, all females, ranging from 15 to 50 years of age. Four were emmetropic. One patient had undergone refractive photokeratectomy a few months before. All had risk factors for infectious complications. The fundamental causes of infections were diverse: bacterial abscesses, keratomycosis, and amoebic keratitis. All presented severity criteria. In two cases, the keratitis led to severe consequences with legal blindness requiring penetrating keratoplasty in one case.Infectious keratitis in plano cosmetic lenses wearers is not rare and may have dramatic consequences. Sales are specifically regulated and the lenses are considered cosmetic products, not medical devices. The sales regulations for plano cosmetic lenses should be updated, as several countries have already done after encountering many serious incidents.Copyright 2010 Elsevier Masson SAS.
